![]() By efficiency, people mean they don’t want to have to email back and forth 3-4 times to get a problem solved or to get clear information about a product, service, or situation.Ĭhecklist: 6 Criteria for Effective Business Writing In addition to the perception problem, clarity and efficiency matter. And fully, one in four workers reported that they’d reconsider doing business with someone and their organization because of poor writing. The publisher’s email brought to mind once again responses from a recent University of Northern Colorado study of white-collar workers: Forty percent said poor writing lessened someone’s credibility. They decide not to do business with the sender, equating their product or service quality with their writing quality.They don’t understand it well enough to respond.They (after a quick glance) dismiss it as “unprofessional” and not worth their time.It is the old economy labels that are making their physical media format less convenient and less valuable by adding various types of defects, not something that is inherent in the underlying format. Whenever I get these files I tend to back them up to DVD/CD anyway, so getting them on CD in the first place is still very convenient. Very few sites offer the files in FLAC or similar standards-based non-defective lossless file format. I seem to either be offered unauthorized/infringing files, low quality MP3 files, or defective DRM’d files (I run a FLOSS only shop, so have no “legal” way to access DRM’d files). In Canada there is a collective society called Access Copyright that would assume that they should be given the right to collect royalties “on your behalf” for any Canadians that access your “freely available” book.Īs to the book/CD analogy: Getting a Red-Book standard audio CD with higher quality audio is for me far more convenient than an “internet download”. The term “freely available” has entirely different meanings for different people, and to avoid lawyers getting in the way you want to have clear documentation (IE: a license). I am curious if the specific license agreement that the online version is offered in can be documented. This question more than any other gives me pause about committing to a publication date. Will Microsoft get remote attestation to work? I am highly sceptical. The elephant in the living room is of course Trusted Computing and Vista. Some technical fields have moved on chip tampering is now more about optical probing than mechanical probing, and real cryptosystem exploits are more about API and system weaknesses. Security usability is much more important, and maintainability too. ![]() The biggest change to online security has been that hackers now don’t work for fun as much as for profit we’ve seen the emergence of a black economy with diversified specialists doing malware, spyware, spam and phishing. The “War or Terror” has in some sense changed everything but in many senses has changed nothing. Maybe I should think of consolidating this into an ‘update chapter’ describing the main things that have changed since 2001. Meanwhile there’s some new material on the book website. ![]() I might do one next academic year, or write a book on something else next year and then do Security Engineering 2e in 2007-8. I do plan to produce a second edition but I haven’t yet signed anything. Let me know if you are interested in the math. But a passphrase 15 characters long that is all lowercase and using spaces will take millions of years to break in comparison. For example if you have a password that has numbers, letters (upper and lower) and special characters but is only 8 characters long, it is extremely feasable to break it in minutes using rainbowtables. The length of the password relates directly on how long it takes to break it not the complexity. Passphrases IMO are better as they are much easier to remember and are significantly longer then a password. And any password/passphrase over 8 characters starts to become impratical in breaking. The most effective means is using a rainbowtable instead of a bruteforcer. I says that because I have broken ALOT of passwords. So the statement you made “So passphrases and random passwords seemed to be about equally effective.” would not be true if you do the math. If it was truely a passphrase the user would have used the phrase “It’s 12 noon and I am hungry” and not just the initials. Thus, “It’s 12 noon and I am hungry” would give I S12&IAH.” “The green group was told to think of a passphrase and select letters from it to build a password. In it you talk about passphrases but I think it should have been changed to just phrase. I do have some criticism for you on the password section.
